atom

Atom is an open-source, self-hosted AI agent platform designed for enterprise-grade automation with built-in governance. It enables teams to delegate tasks to specialized agents (e.g., sales, support, finance) in plain language, with agents operating autonomously within strictly controlled boundaries. Key features include a 4-tier maturity model (STUDENT → AUTONOMOUS) where agents earn trust through verified outcomes, default-on sandboxing (filesystem scope, tool whitelists, resource caps), and postcondition oracles that re-derive success against systems of record to prevent self-reported false positives. Data remains on-premises, with support for BYOK (Bring Your Own Keys) or local models (Ollama, LM Studio, etc.). Atom integrates with 46+ business tools (Salesforce, HubSpot, Slack, Jira, QuickBooks) and supports cost-aware LLM routing across 16+ providers. Workflows can be agent-authored via chat, with human-in-the-loop (HITL) approval gates, full audit trails, and office-native automation (Excel formulas, live co-editing). The platform is AGPL-licensed, with no closed-source components or vendor lock-in.
